摘要 本文论述了街后生态实验场的组建、结构与功能等问题。认为生态场的各种生产项目的物种是食物链上的一个环节,各种生产项目通过食物链的能量流动和物质循环的形式密切联系,形成一个有机整体。通过物质的多层次利用带来的低生产成本具有明显的效益。 Component, structure and functions of the Jiehou ecological experimental farm was described. The authors consider that each species in a production process forms a linkage in a food-chain and various production processes are connected by energy flow and material cycling through food-chains which form a closely related holistic system. The repeated utilization of materials could reduce production costs and thereby significantly enhance efficiency.
